5 Claims. (Cl. 248-279) This invention is directed to an improvement in electric lamp brackets designed to be secured to the wall or other appropriate support and constructed to permit adjustment for varying the distance of .the lamp socket from the support to which the bracket is attached.

The primary object of the present invention is the construction of a bracket of this type which may be inexpensively constructed, both as to material and manufacturing costs, which involves few parts, with the parts so mounted as to permit substantially universal play of the lamp socket and lamp relative to the support to which the bracket is secured.

The invention is illustrated in the accompanying drawings, in which:

Figure l is a perspective view of the improved bracket with the parts in preferred arrangement.

Figure 8 is a longitudinal section at the forward end of the bracket showing the extension arm support.

Figure 9 is a section on line 9 9 of Figure 8.

The invention in the preferred form, as shown more particularly in Figures 1 to 5, inclusive, comprises a wall plate I which may be of any appropriate outline form, being here shown as approximately oval. The wall plate is designed to be secured to a wall or other fixture through the medium of a key-hole opening 2 engaging a tack or like element on the fixture and may, under these conditions, provide a more or less portable xture which may be conveniently moved from place to place. Fixed centrally on the wan plate is a support involving spaced parallel upper and lower ears 3 integral with the section 4 which is secured in any appropriate manner to the wall plate.

The bracket proper is made up of a supporting section 5 and an adjusting section 6 each constructedof relatively narrow thin strips of metal, economical in cost and extremely easy to fabricate. The supporting section comprises a bar of appropriate length, the rear portion of to t between and contact with the ears 3 of the 10 wall plate member, the ears 3 and I0 being perforated to receive a pivot pin II headed at the upper end and threaded at the lower end to receive a wing nut I2, whereby the bracket may be mounted for swinging support with respect to the wall plate with the freedom of swinging movement controlled even to the extent of rendering the parts relatively fixed through the adjustment of the wing nut I2.

The supporting section of the bracket is completed by a bracing member I3, one end of which is secured to the upper portion of the curved portion l of the supporting section, the bracing section extending to substantially the free end of the bar 5 of the supporting section and then 25 35 The adjusting or extension sect1on 6 `1s formed of a flat bar I8 approximating or equal to the width of the main bar 5, with the rear terminal outwardly curved at I9 and terminally coiled at 20 for ornamental purposes. of the adjusting section is mounted for sliding movement through vthe opening I I of the guide section I5, being thus held substantially in contact with the lower surface of the main bar 5 The flat bar ls 40 of the supporting section.

It is to be noted that the upper limit of the coil 20 at the inner end of the adjusting section is so spaced from the main bar I8 of that section as to pass over the guide member in order to permit the full limit movement of the adjusting section with respect to the supporting section. The coil 20 is also preferably of such diameter that it may serve as a finger-hold for moving the adjusting section with respect to the supporting section. Y

The hanger is connected to the terminal portion 2I of the adjusting section by a pivot bolt 21 and cooperating wing nut 28 to ythereby permit the hanger and thus Vthe lamp socket to be arranged at any angle with respect to the adjusting section and secured in that position for control of light direction. The energizing lead 29 from the socket 26 extends through an opening 38 in the curved portion I9 of the adjusting section, the lead being of sufficient length to permit maximum I adjustment of the section I5, when desired.

In the form shown in Figures v6 to 9, inclusive, the main bracket construction is substantially identical with that shown in the preferred form except that the relative positions of the supporting section and adjusting section are reversed. Here the supporting section, indicated generally at 32, comprising a iiatbar 33 curved at 34 at the rear end and Vterminally coiled at 35 Vfor ornamental purposes, fvurther includes a brace section 36 extending from the curved end 34 to the bottom of the flat bar portion `33 -and terminally Y coiled at 31 beyond the flat bar 33.

Thebar 33 of the supporting section is provided on its upper Vsurface with a guide 38 having upturned ends 39 slotted lat 48 to slidably receive the adjusting section Ymade -up -of .a flat bar 4I slidable through the openings -40 and coiled at the rear end, as at 412, to provide -anzoperating ringer-hold. The flat bar -of the adjusting sec- 'tion is given a half twist -at its forward end to provide a vertically arranged part 43 -on -whichis supported'a hanger-44 connected to -the -adjusting section in a manner and as to form similar to that in the construction previouslydescribed. A conventional lamp socket 'T45 is 'supported from the hanger through a bracket 46 fexactlyas in -the .preferred form.

In this form the wall plate L4-I `is of oval shape having akey-hole supportingopening 48 at the upper end and preferably centrally domed at 49. A pivot rod lI) has its'terminalsbrazed or 4otherwise secured to the domed portion 48 of the Vwall plate and presents a vertical pivot-section v5I spaced from the domed portion.

The curved portion 34 -of `the supportingsec- Ation is offset to provide upper and lower ears 52 connected by a Vvertical wall 53 at their outer ends, this construction being integral with the supporting section. The ears 52 are formed with openings to receive the pivot section 5I of the pivot rod 5U, permitting free swinging of .the bracket as a whole with respect to the wall plate. The energizing lead 54 vof Vthe socket 45 extends through an opening 55 -in the supporting section.

It will be understood that while the respective forms illustrated and vdescribed constitute pracltical reversals'in arrangement and are otherwise substantially identical, they differ more particularlyin the Ymeans for pivotally supporting the bracket vasa'vvhole with respect to the wall plate.

section, said adjusting section comprising a flat `bar terminally formed at the inner end with a finger coil for operation of the adjusting vsecnormal plane of the flat bar, a socket-supporting hanger pivotally carried by said short length 'for swinging adjustment relative thereto, and rmeans for securing the hanger in any .desired 'relation to' the -flat bar.

formed and brazed or otherwise secured to the particular parts with which they cooperate. In the modied form, the pivot pin is a fixed part of the wall plate while thecooperating pivot section on the bracket is an integral part of the 5 supporting section of that bracket. In this form, there is complete freedom of swinging movement Without control vof fixation.

It is to be particularly understood that while one form of pivot mounting is shown in connec- Vtion with the preferred form and a second form of pivot mounting is shown in connection with the modiiied form, these respective pivot mountings may be used either one to the exclusion of Athe other, that is the pivot mounting of the preferred form may be used with the modied form and the pivot mounting of the modiiied form may be used with the preferred form whenever such .may rbe desired.

It is tok be particularly noted that in the .prelferredforrn the flat bar I8 of the adjusting section underlies the flat or main bar 5 vof the supporting section. Thus, inany adjustment of the section aportion of the main bar I 8 of thatsection will be held against upward movement of the main bar 5 'of the supporting 'section and thus'provide 'further rigidity and more effective supporting action for the lamp carrying end of the adjusting section, Vthus permitting the material used to be vcomparatively thin and yet supvr port evena cluster of lights at the free end and through the full extended position of the section 6. In the modifledform, the adjusting section is supported on top of the main `bar33 of the supporting section andthe guide lips '39 will serve 35` more or less efficiently to prevent tilting 'of the bar 4I of the supporting section under 'thewei'ght of the lamp and its connections.

What is claimed to be new is:
